Today Microsoft announced that its ‘Bing It On Challenge‘ has scooted past the 5 million visit mark. According to its blog post, that figure is in excess of its projections. I would certainly think so.The number of visits should be not be taken to indicate user discontent with Google however; the brazenness of the challenge led to a very large, and somewhat positive press cycle, which drove the traffic. As TNW reported previously:Microsoft is making a bold move today, launching a new blind test that pits Bing against Google in efforts to show how useful its search results are compared to the old standard. Microsoft explains on its blog that this is a “non-scientific test,” but claims upfront that research shows “people prefer Bing web search results over Google.”
